TTI Infinity Hi-Capa Hop-Up Chamber

The TTI Infinity Hi-Capa hop-up chamber is a high-quality internal upgrade component engineered for Hi-Capa and 1911-platform gas blowback pistols. Proper hop-up adjustment is essential for consistent accuracy and extended effective range; a precision chamber like this TTI Infinity model ensures your BB trajectory remains flat across varied engagement distances, whether you’re running a CQB pistol loadout or a secondary support weapon role.

Key Features

• TTI Infinity Design – engineered for Hi-Capa and 1911 GBB pistols with refined geometry to maximise BB contact and hop-up consistency.
• Precision Hop-Up Control – allows fine-tuning of backspin for improved accuracy and trajectory stability across engagement ranges.
• Enhanced BB Compatibility – performs reliably with standard 0.20 g and heavier BB weights (0.25 g–0.30 g), adapting to your site’s FPS limits.
• Direct Drop-In Fit – straightforward installation on compatible Hi-Capa and 1911 models without permanent modification.
• Durable Construction – built to withstand repeated gas blowback cycling and regular use in skirmish and milsim environments.

Real-World Use Cases

• CQB Indoor Pistol Play – hop-up precision is critical in tight indoor sites; this chamber supports consistent short-range engagements with minimal drift.
• UK Woodland Milsim – as a secondary support weapon or primary loadout, reliable hop-up adjustment extends your effective pistol range and aids target acquisition at distance.
• GBB Pistol Tuning – ideal for players upgrading their Hi-Capa or 1911 platform to match upgraded spring setups or to improve accuracy on heavier BBs (0.28 g–0.30 g) favoured by many UK sites.

UK Legal & Site Notes

This is an internal upgrade part intended for use on fully licensed airsoft replicas (RIFs). Ensure your GBB pistol complies with UK law and your local skirmish site’s FPS limits (typically 1.13 joules / ~350 FPS for pistols). Always chrono your setup before play and check your site’s BB weight restrictions—many UK sites mandate 0.25 g or heavier BBs. This part does not alter the legal classification of your replica.
